That weedy little girl voice of her early recordings was thoroughly loathesome IMO and she was nothing more than a 'product'. So a bit of a jaw dropper where she say's (paraphrased): "if I hadn't have been discovered, I'd have sung Mozart" - represents rather a profound overestimation of her own talents IMO.
I do like the rough sound she makes now far more however. Jury's out on whether I feel her craft is that engaging or worthwhile though.
